Shamrock Shake Lasagna Ingredients
For the Crust
• Oreos – These crushed cookies create a sweet and crunchy base; swap with chocolate sandwich cookies if desired.
• Butter – Adds richness and binds the crust; opt for unsalted for better control over flavor.
For the Cream Cheese Layer
• Cream Cheese – Provides a creamy base that balances sweetness; use full-fat for a dreamy texture.
• Powdered Sugar – Sweetens the cream mixture, making it silky smooth; granulated sugar can be used but will change the texture.
• Cool Whip – Adds fluffiness to the cream layer; homemade whipped cream is a great, non-processed alternative.
For the Pudding Layer
• Milk – Mix with the pudding for creaminess; feel free to choose whole, low-fat, or even non-dairy options.
• Cheesecake Instant Pudding Mix – This gives flavor and thickness; only instant variety works for this recipe.
• Mint Extract – Infuses a refreshing mint flavor; adjust the amount based on your taste preference.
• Green Gel Food Coloring – Imparts that festive mint green color; add sparingly until reaching your desired hue.
Optional Topping
• Crushed Oreos – Sprinkle on top for extra texture and crunch; or try crushed mint candies for an added minty punch.
This Shamrock Shake Lasagna is sure to be a delightful centerpiece to celebrate St. Patrick’s Day!
Step‑by‑Step Instructions for Shamrock Shake Lasagna
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While it heats up, grab a 9×13 inch baking pan and lightly spray it with non-stick cooking spray to prevent your dessert from sticking. This preparation is crucial for creating the perfect base for your Shamrock Shake Lasagna.
Step 2: Crush the Oreos
Using a food processor, crush 36 Oreos until they turn into fine crumbs, resembling sand. This process should take about 30 seconds. If you don’t have a food processor, placing the cookies in a zip-top bag and crushing them with a rolling pin works too. Achieving fine crumbs will ensure a uniform crust for your lasagna.
Step 3: Mix the Crust
In a large mixing bowl, combine the crushed Oreos with ½ cup of melted unsalted butter. Mix thoroughly until the Oreos are fully coated and the mixture becomes slightly sticky. This will help bind the crust together. Once mixed, it’s ready to be transformed into a lovely foundation for your Shamrock Shake Lasagna.
Step 4: Press and Bake
Transfer the Oreo mixture into your prepared baking pan, pressing it down evenly with the back of a measuring cup or your hands. Make sure it’s packed tightly for stability. Place the pan in the preheated oven and bake for 8 minutes, then remove it and allow the crust to cool completely at room temperature.
Step 5: Prepare the Cream Cheese Layer
In a mixing bowl, beat together 8 oz of softened cream cheese, 1 cup of powdered sugar, and 8 oz of Cool Whip until smooth and creamy. This should take about 2-3 minutes using an electric mixer. Once well combined, spread this delightful mixture evenly over your cooled Oreo crust, creating a luscious first layer.
Step 6: Whisk the Pudding
In a separate bowl, whisk together 3 cups of milk and 3 boxes of cheesecake instant pudding mix for about 2-3 minutes until well combined and thickened. The pudding will create a creamy layer that complements the cream cheese beautifully. Be sure you’re using instant pudding mix for the right texture in your Shamrock Shake Lasagna.
Step 7: Fold in the Mint and Color
Gently fold in another 8 oz of Cool Whip and your desired amount of mint extract into the pudding mixture, ensuring it’s well incorporated. This will enhance the minty flavor of your lasagna. Then, add a few drops of green gel food coloring and mix until the color is evenly distributed and reaches your preferred festive shade.
Step 8: Spread the Mint Layer
Carefully spread the mint pudding layer over the cream cheese layer in your baking pan. Use a spatula to smooth it out evenly, ensuring every bit of the creamy filling is in place. This vibrant layer will be the star of your Shamrock Shake Lasagna, providing both flavor and color.
Step 9: Add the Final Touch
If you like, sprinkle additional crushed Oreos on top of the mint layer to give your dessert a crunchy finish. This adds a nice texture contrast and enhances the overall appearance. Once topped, cover the dish with plastic wrap or foil, and refrigerate for at least 4 hours, or overnight, for the best results.
Step 10: Serve and Enjoy
After your Shamrock Shake Lasagna has chilled and set, slice it into squares and serve cold. Each piece showcases beautiful layers that are sure to impress. You can garnish with whipped cream or fresh mint leaves for an extra touch when serving. Enjoy the delightful flavors and creativity of this festive dessert!

Make Ahead Options
These Shamrock Shake Lasagna layers are perfect for meal prep enthusiasts looking to save time! You can prepare the crust and cream cheese layer up to 24 hours ahead by simply covering and refrigerating them. Additionally, the mint pudding layer can be mixed and set in the fridge for 3 days before serving—just keep it well-covered to maintain its freshness. When you’re ready to serve, layer the prepared mint pudding over the cream cheese, sprinkle with crushed Oreos, and refrigerate until firm (preferably overnight). This way, you’ll have a show-stopping dessert ready with minimal effort, ensuring it’s just as delicious and festive when you’re ready to celebrate!
